Search For A Massive Resonance Decaying Into A Higgs Boson And A W Or Z Boson In Hadronic Final States In Proton-Proton Collisions At √s = 8 TeV
Journal of High Energy Physics
A search for a massive resonance decaying into a standard-model-like Higgs boson (H) and a W or Z boson is reported. The analysis is performed on a data sample corresponding to an integrated luminosity of 19.7 fb-1, collected in proton-proton collisions at a centre-of-mass energy of 8TeV with the CMS detector at the LHC. Signal events, in which the decay products of Higgs, W, or Z bosons at high Lorentz boost are contained within single reconstructed jets, are identified using jet substructure techniques, including the tagging of b hadrons. This is the first search for heavy resonances decaying into HW or HZ resulting in an all-jet final state, as well as the first application of jet substructure techniques to identify H→ WW*→ 4q decays at high Lorentz boost. No significant signal is observed and limits are set at 95% confidence level on the production cross sections of W’ and Z’ in a model with mass-degenerate charged and neutral spin-1 resonances. Resonance masses are excluded for W0 in the interval [1.0, 1.6]TeV, for Z0 in the intervals [1.0, 1.1] and [1.3, 1.5]TeV, and for mass-degenerate W0 and Z’ in the interval [1.0, 1.7]TeV.
